The agnostic and evolutionist Carl Sagan was an avid marijuana smoker who claimed marijuana gave him scientific insights.[4] Given the lack of any real evidence for the evolutionary position and the aforementioned abundance of evidence against the evolutionary paradigm, Sagan's agnosticism and avid marijuana smoking no doubt helped inspire Sagan's pseudoscientific fantasy that evolution was a "fact".[5]Thomas Henry Huxley, the English biologist, known as "Darwin's Bulldog" for his vehement advocacy of Charles Darwin's theory of evolution, was an agnostic. The Barna Group found that those who hold to the worldviews of agnosticism or atheism in America were more likely, than theists in America, to look upon the following behaviors as morally acceptable: illegal drug use; excessive drinking; sexual relationships outside of marriage; abortion; cohabitating with someone of opposite sex outside of marriage; obscene language; gambling; pornography and obscene sexual behavior; and engaging in homosexuality/bisexuality (see also: atheism and morality).
